Patented Feb. 16, 1943 Application June 11, 1942, Serial No. 446,671 40mins 1. 164-845) I This,invention relates to an apparatus for dispensing pressure-sensitive tape from a roll and the object of the invention is to provide means whereby a predetermined length of tape may be dispensed.

Another object of the invention is to provide a pressure-sensitive tape dispensing means wherein the length of tape to be dispensed may be varied at will. i

Still another object of the invention is to provide an adjustable means for limiting the movement of a lever handle which operates the roll of tape.

I accomplish the above and other objects of the invention, which will be apparent as the description proceeds, by means of the construction shown in the accompanying drawings, in which Fig. 1 is a perspective of the ing my invention;

Fig. 2 is a side elevation of the construction constituting my invention, the parts on the interior of the casing being shown in dotted linesj Fig. 3 is a section on the line 3-3 of Fig. 2, looking in the direction of the arrows;

Fig. 4 is a section on the line {-4 of Fig. 2, looking in the direction of the arrows;

Fig. 5 is a side elevation of the device constituting my invention, the casing and sliding rack being shown in section and the extended position of the slidingrackbeing shown in dotted lines;

Fig. 6 is a side elevation of the front portion of the casing showing a modified form of rack stop;

Fig. 7 is a section on the line 1-1 of Fig. 6, looking in the direction of the arrows; and

Fig. 8 is a perspective of the parts constituting the adjustable rack stop pin shown in Figs. 6 and 7.

On the drawings, in which like reference chardevice constitutacters indicate like parts on all the views thereof,

I indicates the casing for the tape roll 2 and the dispensing means therefor, the tape roll being carried by the shaft 3. 4 indicates the sliding rack, having an upstanding tape cut-off 5 to which the end of the tape is temporarily secured by its pressure-sensitive face.

The rack! has teeth I, which mesh with the teeth 8 of the gear wheel 9 mounted on the shaft l0. Secured to the shaft I0 is the operating lever handle II, by means of which the gear wheel is rotated to cause the rack to slide forward in the grooves 12 of the casing, against the action of the spring l3, carrying with it the stripof tape as it is unrolled from the tape roll 2.

Secured to the front ,end of the casing is an' arcuate strip of metal or other suitable'material I 4, through which is'bored a series of holes IS, the holes also extending through the casing wall. While the arcuate strip of material is here shown as being secured to the outer face of the casing, it is obvious that it may be located on the interior wall of the casing, if so desired since its purpose is to reinforce the casing wall where the holes 15 are located. .The holes l5 are for the reception of the adjustable pin; stop 16, which is shown as connected to the casing by the chain l1.

The upstanding cut off 5 is provided with a cutting edge I8 by means of which the dispensed strip of tape is severed from the roll. v In operation, the pin stop I6 is placed in one of the holes l5 and the end of the tape stuck to the cut-off 5. The handle lever II is rocked forward, thereby rotating the .gear wheel 9, t

which in turn slides the rack forward against the action of the spring l3. When the handle lever abuts the pin stop Hi, the end of thetape v is stripped from the upstanding cut-off and the handle lever released, whereupon. the sliding rack I. will return to its initial position with theQOut-ofl at the front end of the casing, as shown in full lines in Fig. 5. The dispensed strip of tape can y then be torn off by contact with the cut-off edge.

It is thus .apparentthat the length of tape.

dispensed'is determinedby the'position of the handle lever stop 18 whichdefi-n'es the limit of strip.

In Figs. 6 to 8, inclusive, 1' have shown a modi- I fled form-ofthe handle lever stop'constructiom' in which the casing is providedwith an arcuate slot 20, there being a series of pairs of slotsll: leading therefrom. The pin stop has a knurled.

portion 22 terminating in a collar 23 against" which abut the lugs 24 of the collar 25 which is held in place by means of thenut 2,6, which is screwed on to the end of the pin stop.

In this construction, the pin is mounted on the casing by positioning the lugs 24in the'desired pair of slots and the nut 26 tightened, thus making a rigid assembly. The pin can be moved from one position in the arcuateway to another by merely loosening the nut so that the lugs may be freed from the pair of slots in. which they are located.

It will thus be seen that by means of my improved construction, tape may be dispensed and cut off in predetermined lengths, thus eliminating guess work with the resulting wastage of tape. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: r 1. In a pressure sensitive tape dispensing device, a casing, a tape holding roll in said casing, a tape dispensing slide' beneath and spaced from said roll and-the tape carried thereby, a handle for operating said slide, a stop for limiting the movement of the handle, there being a plurality of seats for said stop in said casing. a

2. In a pressure-sensitive tape dispensing device, a casing, a support for a roll of tape in said casing, an inclined tape dispensing slide beneath and spaced from the support and the tape carried thereby, a cut-off on said slide, means for operating said slide, means for limiting the movement of said first named means, and means whereby said second named means may be located in any one oi. a plurality of positions on the casing in the path of movement of the first named means;

3. In a pressure-sensitive tape dispensing device, a casing, a tape carrier in the upper portion of said casing, a tape dispensing slide mounted within said casing beneath and spaced from said carrier and tape carried thereby, an upstanding cut of! on said slideihaving a face to 'which' a portion of the tape may be temporarily secured, the parts being so constructed and arranged that the tape is at all times spaced from the main portion of the slide.

4. The construction described in claim 3 in which the said face is at an angle to the upstanding portion of the cut off.
